    The invention relates to devices for loading vented or open containers for fine-grained bulk materials in a pneumatic-chesty transport system, in particular, with an aerosol transport.
    The purpose of the invention is to simplify and reduce energy consumption.
    Fig, 1 shows the proposed device, a vertical section; figure 2 - execution of a flexible shell in the form of bellows; fig.Z - the same, in the form of a molded membrane; figure 4 - the implementation of the lower part of the pipe-shell with a locking body; in FIG. 3, the upper storage area with an inserted device at the beginning of the loading process; in Fig. 6 - the same, while loading 1: a fine fine-grained bulk material reaches the pipe shell; 7 - the same, at the end of the loading process with a locking body located at the top.
    The device (FIG. 1) contains a pipe shell 1, a lifting member 2, a locking member 3 for: a bare open end of the sheath pipe 1, a pull 4 that connects the lifting 2 and locking 3 organs at an adjustable distance.
    The lifting member 2 consists of a double bellows 5, which is mounted on the upper flange 6 of the shell pipe 1 fe upwards, made of synthetic rubber, and the double sylph 5 is closed with a flat metal top plate 7. B. The zone of the longitudinal axis A of the shell pipe 1 ton ha 4 is welded to the upper plate 7 and enters the shell axially into the tube. one, .
    In the upper part, the casing pipes 1 are placed diagonally opposite two slightly inclined in the upward direction of the nozzle 8, which are connected to the supply pipe 9 and serve as a supply pipe or outlet in the system with aerosol transport. The compressed air pipe for compressed air for pneumatic conveying is marked with a colored line.
    In the casing pipe 1, two guides are fixed at a certain distance, which consist of two rectangular arms 11 and sleeves 12 for the thrust rod 4, -.
    In the lower part of the gy 4 is fixed with nuts 13 made as

    The valve body 3 is shut off in the direction of the upwardly truncated cone 14 that narrows in the upward direction, with a thread 4 in the lower part provided with the corresponding thread 15.
    On the tapered surface of the truncated cone 14, the truncated circle B is indicated, which exactly corresponds to the volume of the inner cross section of the pipe-shell 1. The distance h of this truncated circle B from the lower edge 16 of the pipe-shell 1 corresponds to the height of the B-shaped bellows 5 lifting device 2, as seen from the position of the shutter.
    The inner diameter d of the pipe-shell 1 limits the surface F ,, the inner diameter D of the bellows 5 - the surface F..
    The dead weight of the locking member 3, the gy 4 and the movable part of the lifting member 2 tightens the double bellows 5. Metal rings 17 with protruding stops or holes, respectively, passing in the radial direction, prevent the bellows from completely closing.
    The lifting unit 2 (Fig. 2) is made of a metallic wavy hose 18, while the ha 4 through the hinge 19 is fixed on the upper plate 7. Thus, the th ha 4 in the α-tube-shell 1 can perform free swing movements, if freedom its movement is not limited to a guide in a metal pipe.
    The lifting element (Fig. 3) is designed as a tiltable membrane 20 capable of tilting. BepxHeSj achieved in the presence of pressure, the position is indicated by a dashed line. The tube 4 through the ball joint 21 is fixed on the membrane 20. Or on the holder 22, respectively. Thus, the rod 4 in the shell-tube 1 is movable to all sides and centered by retraction of the locking member 3, made in the form of a truncated cone 23.
    Zaporny body 3 (figure 4) is made as a hollow, open in a downward direction, hemispheres 24, which is mounted on t 4 with two nuts 13. Lifting body 2 is shown in a raised position, inside the pipe-shell 1 and the lifting body 2 is growing pressure. The bottom edge 25 of the metal pipe contributes to the best ten

    In this case, the nest is inserted as a 0-ring-made seal 26, which is directly adjacent to the ball surface of the hemisphere 24.
    In the devices (Figures 5-7) placed in the alumina storages, only the upper part is shown, and the loading process is shown. The alumina tanks 27 have at least one vent pipe 28 or a suitably designed ventilation casing, with its upper edge 29 being positioned so that air can flow freely, but the incoming bulk material cannot reach this inlet from - for the presence of the corner backfill. In practice, the storage 27 is locked from above and the sheath pipe 1 is fixed in the filling (filling) openings.
    Alumina 30 (FIG. 5) with the necessary 25 for aerosol transport by the amount of air through the supply nozzle 8 reaches the device. Due to its own weight, having the shape of a truncated cone of the locking member 3, d-t gi 4 and the flexible plate 7 consisting of the bellows, the feeding organ 2 is in the compression position. The alumina 30 passes through the truncated cone to the storage 27, the air enters the tank and through the ventilation duct 28 into the surrounding space.
    This filling process is continued until alumina is 30. will not reach the lower edge 16 of the pipe- shell 1 (Fig.6). In this case, the free flow of air into the alumina storage 27 is reduced, and during subsequent filling is completely interrupted. So in pipe35

    The organ 3, after passing the stroke h, hits the lower edge 16 of the pipe-shell 1 and fits tightly against the shell-tube 1 (Fig. 7).
    After locking the first alumina storage for the fine-grained bulk material, there is no more air with the least resistance, all the alumina is fed to the next storage where the proposed device is provided. The same filling process is repeated there (figs. 5-7).
    The last alumina storage in the row contains a level switch which, with full storage, shuts off the installation for aerosol transport.
